High CPU Usage

I have Steam Edition of this program, upon bootup, maybe 1 time out of every 10, the System CPU usage is through the roof. as shown in the capture.

I am unable to load displayfusion settings, and my start menus on secondary screens do not load. after this occurs and i end the process when i restart, Steam prompts for its password and performs the setup again.

I have a memory dump from the locked process, however i do not want to share here publicly due to the specifics you can glean from the dump.

any suggestions on how to troubleshoot?

This may be related to an issue we're currently trying to track down. Could you try rolling back to 8.1.2 to see if this still happens?

You can install it from here: https://www.displayfusion.com/OldVersion/, and just install it over top of your Steam install. It will keep your license and settings. You can just ignore the update prompts after rolling back to 8.1.2 while you test.

Hi Keith,

Just to add to FuzzyLogic's post, I am having the same intermittent issue.

If I "End Task" on DisplayFusion and reopen it is fine - looks like something breaks it when it is loading initially only.

I also will try reverting back a version to see if it helps.

Cheer,s Ben.

I do not have the Steam edition. I'm using DisplayFusion Pro 9.1 and running into this issue -- like other posters, not every startup, but often enough to be noticeable (and annoying), and it's never happened before, though I don't know if when it started is related to a DF patch, a Microsoft patch, or just the phase of the moon.

When this occurs (and it only happens on Windows startup), I have to kill all DF processes manually. The DisplayFusion Service is typically using between 75 and 85% CPU, constantly, while this is happening, and interacting with the systray icon is slow and intermittent (anywhere up to 30 seconds before a window appears, if it appears at all, and nothing works in the window anyway).

I'm going to roll back to 8.1.2 and see if that clears it up. If a logfile or my system stats would help, let me know.

@Brian: How did the roll back to 8.1.2 work out?

@Keith: since rolling back the problem has vanished, and DF is again working as expected without any issues during startup. CPU usage is down to a fairly steady 0.3 to 0.8%.

If it helps diagnose any, I'm running Windows 10 Pro on an Intel i7-7700 @ 3.6GHz, 16GB RAM, and the boot disk that DF loads from is a SSD. I have 3 identical displays on a GeForce GTX 1060. As I said before, if detailed specs or a logfile (assuming there is one) would help, I can provide those.

Thanks Brian! We will definitely let you know if we need any more info. Otherwise, we'll just follow up when we think we've gotten it all fixed up

Hi Keith,

For me with DF 9.1, it is not at startup, but more rarely 99% utilization under heavy usage. But in my situation, Windows 7 Pro (2 large monitors), with many processes and windows open. It is not easily re-created, but when it does happen, killing all resident DF processes, restarting the DF resolves the issue. I am often using evernote, chrome (incognito many tabs/windows), office 2013 (Excel, Powerpoint, Outlook) and often shooting windows to other monitor. When it does occur, I cannot get active windows to be responsive. I always Start with Windows and leave on Check for Updates Automatically.

Is there anything I should be trying to do in Task Manager at the time it occurs to help isolate? I usually am sorting by CPU Time (descending), and most other processes are below 1% when I am in the midst of the issue.

Would you be able to try out DisplayFusion 9.2 Beta 1 to see if the issue still exists?

My issues were rare before, and I have had no so far with reoccurrence with 9.2 Thank-you Keith

I have some hopefully very good news! I was finally able to reproduce the runaway CPU consistently here, and we're 99.99999% sure that we've gotten it fixed up. We released 9.3 this morning, but then found and fixed the CPU bug, so we've reposted it as DisplayFusionSetup-9.3c.exe. If you've already updated to 9.3, could you re-download it from our website and install it? Double-check that the setup file downloads as DisplayFusionSetup-9.3c.exe.

Thanks!

I updated to 9.3 this morning, how do I know if I'm on 9.3c? When I go settings > check for update, it tells me I'm on the latest.

If you go to the "System Information" section on the Troubleshooting tab, what's the build date/time?

E: BTW, you said that you are able to reproduce this CPU issue consistently, I haven't noticed anything CPU related, but what triggers it?

I was able to trigger it intermittently but fairly frequently by unplugging and plugging monitors in, but it's possible that other scenarios could have triggered it as well. It was a somewhat generic threading issue.

Hi,

I am getting consistent CPU usage from DF of 10%-15% and am running the latest build:

• Name: DisplayFusion Pro 9.3
• Name Data: DisplayFusion
• Build Date: Jun 27, 2018 17:45

My question is what sort of CPU would be considered normal? I realize this is dependent on my configuration, but without uploading it all (attached) I was wondering if you can give me an idea of what sort of ball park CPU I should expect, to know if I even have a problem or this is just normal usage?

Thanks,
Andy

@Andrew: That's definitely not normal. Most of the time it should be under 5%, and usually 1-3%. Could you attach a debug log? Here are the steps:

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Reproduce the issue and note the time so we'll know where to check in the log file
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Also, if you enable the "Disable Application Hooks" option in the Settings > Advanced Settings window and restart DisplayFusion, does that make any difference at all?

Hi I am experiencing the same issue where DisplayFusion Pro 9.3 regularly spikes my CPU usage to 99 - 100%. I am running this version on a Windows 10 Pro laptop. I typically will have to end task for DisplayFusion and then my CPU usage will drop back down to the 30 - 40% range. I read in the thread above that you recommended that updating to the beta version of DF 9.3 might be a possible solution.

Please advise if you have had good results with DF 9.3 users updating to the beta release on resolving this issue (at least temporarily).

Thank you.

Thanks! I noticed that you're running Bins as well. A long time ago we had an issue where when Bins was running, the DisplayFusion CPU usage would increase. If you disable Bins and restart DisplayFusion, does that make any difference?

It seems to have helped to disable Bins. I will need to test more fully to confirm that this interaction between DFP and Bins was the issue.

Thanks.
